Rated 5 out of 5 stars
Great add-on, I really wonder why this is not factory built in TB. Many thanks to the developer!
(1) It would be nice to have an option to align left the buttons as well (mine align to the right)
(2) It would be great to have the "unavailable functions" in a message (such as "Smart reply" when there's just one recipient) being greyed-out instead of removed, so that the order and placement of buttons doesn't change from one message to another.
